SPECIFICATION forming part of Letters Patent No. 326,777, a ed S pt m e 22, 18 5.

Application filed July 9, 1885.

T aZZ whom it may concern:

Be it known that I, J osnrn 0. Ports, a citizen of the United States, and a resident of Berwyn, Chester county, Pennsylvania, have in vented an Improved Device for Converting Motion, of which the following is a specification.

The object of my invention is to construct a device whereby a uniform vibrating or recipro rocating movement in one direction may be transformed into a differential reciprocating movement in another direction; and this ob ject I attain in the manner which I will now proceed to describe, reference being had to the accompanying drawings, in which Figure 1 is a side view of a device embodying my invention; Fig. 2, a front view of part of the same, and Figs. 3, 4, 5, 6, and 7 detached views illustrating details in the con struction of the device. Fig. 8 is a view representing certain modifications of the invention.

The mechanism forming the subject of my invention may be applied to various uses in 2 5 which it is desired to transform a vibrating or reciprocating movement of uniform extent into a differential movement in another direction. The mechanism, for instance, may be used for operating the drop-boxes of a loom, or for shift- 0 ing blocks on the platen of a color-printing press, or other purposes, the device being shown in the drawings, for convenience, as applied to the operation of the shuttle-boxes of a loom.

A is one of the fixed side frames of the struct- 5 ure, and B a pivoted frame, which in this case is the lathe of the loom. This frame has at the upper ends guides for the boxes D,to which a differential movement is to be imparted, these boxes being carried by a guided rod, a.

To this red is secured a bracket, 1), from which projects a pin, (1, adapted to a slot, (1, in a cam, F, the latter being secured to a shaft, 9,

which is confined laterally to, but is free to turn in, a bearing, 0, upon the frame B.

Secured to the frame B is a notched disk, f, with which engage lugs 'i on a collar, 0, the latter being free to slide on the shaft 9, but being prevented from turning independently thereof by a key-seat and feather or equivalent means, and being acted on by a spring, h, the

outer bearing of which is against a fixed colo model.)

lar, h, the tendency of said spring being to maintain the lugs i in engagement with the notches of the disk f.

Hung to a fixed arm, k, projecting from the frame B is an arm, H, having a toothed segment, 1, which gears into a spur-wheel, G, on the shaft 9, said arm H also carrying projecting arms J J, which form in effect the two arms of a lever having the arm as its ful- 6 erum, these arms being in the path of the projecting ends of bolts M, suitably guided on the frame A, the ends of these bolts being connected to opposite arms on a lever, N, another arm, N, of which has a pivoted arm, N, 0011- 6 nected by a rod, m, to a lever, m, the latter being connected by a rod, a, to a weighted arm, P, pivoted to the frame A, and acted upon by the pins of a pattern-chain, S.

The frame B is intended to be vibrated and 70 the drum of the pattern-chain intermittently rotated from some shaft of the machine of which the device forms part, so that there will be a movement of the pattern-chain to the extent of one pin for each vibration of the frame B. As the frame swings forward it carries with it the shaft 9 and arm k, and the arms J J of the arm H are brought into contact with the projecting ends of the bolts M.

If the upper bolt is projected so as to strike and move the upper arm, J, there will be a corresponding movement of the segment I, spur-wheel G, and cam F, so as to effect a raising of the rod a, while if the lower bolt is projected so as to strike and operate the arm 8 J there will be a movement of the parts in the opposite direction and a lowering of the rod a, the extent of either movement being governed by the extent of projection of the bolt, and this being under the control of the 9c pins of the pattern-chain through the medium of the levers and rods before described. The shaft 9 after each adjustment is locked by the engagement of the lugs z of the collar 0 with one or other of each set of notches of the fixed disk f, the tension of the spring It being such that while it can be easily overcome when the arms J J are subjected to the action of the bolts M, it will prevent the accidental displacement of the shaft g and the parts carried thereby.

In order to prevent breakage of any of the parts when there is any obstruction preventing the movement of the boxes or other devices conneeted to therod a, the arms J J are pivoted to the arm H,.and are under the influence of a spring. H, carried thereby, so that the movement of either arm J J is transmitted to the arm H through the medium of this spring, the latter yielding whenever there is any undue resistance to the movement of the arm and its segment I.

The object of making the arm N movable independently of the arm N of the lever N, as described, is to permit the locking of said lever after it has been adjusted to the proper position.

Upon the frame A is an arm, 19, terminating in a notched segment, 8, with which is adapted to engage one end of a bolt, 1, guided on the arm I, and recessed at the outer end for adaptation to a double cam, 12, on the arm N". The movement of this arm N in either direction independently of the arm N is limited by the contact of the outer end of the latter with lugs 10 on the arm N, the effect of the first movement of the arm N in either direction before the lug w of said arm strikes the end of the arm N being to cause the earn 1) to act upon the bolt 25 and withdraw the inner end of the same from the notched segment 8, so as to permit the movement of the lever N, which operates the bolts M.

The weighted arm 1?, upon which the pins of the pattern-chain act, has a notch, 00, so that after each lift of the arm there is a slight drop of the same, in order to restore the arm N to the mid-positiomand thereby thrust the bolt it into one of the notches of the segment 8 and lock the lever N in the position to which it has been adjusted. \Vhen the support of either pin of the pattern-chain is removed from the arm I, the latter falls to its full extent, and is then lifted again to the proper extent by the succeeding pin, the bolt t being withdrawn from the notch of the segments as the arm 1? commences to fall, and being re applied to a notch of the segment as the said arm, owing to the presence of the notch 00, again drops slightly after its new adjustment.

Various modifications of the device within the scope of my invention will readily suggest themselves. For instance, the arms J J might be hung to a sleeve on the shaft 9, the arm H and segment I being dispensed with, and an arm on the shaft 9 may be connected by a rod to a pin on the rod a, in place of using the slotted cam and pin, as shown. I claim as my invention (See Fig. 8.)

1. The combination of a vibrating or reciprocating frame, a rod guided thereon, but free to move in a direction different from that of the movement of the frame, a lever hung to the frame, means whereby the movement of the lever is transmitted to the rod, and adjustable bolts acting upon the opposite arms of the said lever as the frame vibrates or reciprocates, as specified.

2. The combination of a vibrating or reciprocating frame, a rod guided thereon, but free to move in a direction different from that of the movement of the frame, a lever hung to the frame, means whereby the movement of the lever is transmitted to the rod, adjustable bolts acting on the opposite arms of the lever as the frame vibrates or reciprocates, and a pin-chain or pattern device for adjusting said bolts, as set forth.

3. The combination of a vibrating or reciprocating frame, a rod guided thereon, but free to move in a direction different from that of the movement of the frame, an operating-lever therefor having spring-arms J J, bolts for acting on said arms, and a pattern-chain for adjusting the bolts, as specified.

4. The combination of the vibrating or reciprocating frame, a device to be moved thereby, an operating-lever therefor, having arms J J, bolts for acting on said arms, apattern-chain for adjusting the bolts, and a locking device for retaining the bolts in the position to which they are adjusted, all substantially as specified.

5. The combination of the vibrating or reciprocating frame, a device to be moved thereby, an operating-lever therefor having arms J J, a spring-retainer for holding the device in position in the intervals between its movements, and adjustable bolts for acting on the arms J J, to cause the movement of the device, as specified.

6. The combination of the bolts M with the lever N, having a pivoted arm, N with stops to and double cam o, the notched segment 8, the bolt it, an arm, 1?, connected to the arm N and having a recess, x, and a pin-chain for acting on said arm 1 as set forth.

In testimony whereof I have signed my name 105 to this specification in the presence of two subscribing witnesses.
